[Bug 1692215] Re: package grub-pc 2.02~beta2-36ubuntu3.10 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

[Jerry Bezencon]

Confirmed here. Looks like the postinst file has an extra 'fi' at line
703 of that file.

Title:
  package grub-pc 2.02~beta2-36ubuntu3.10 failed to install/upgrade:
  subprocess installed post-installation script returned error exit
  status 2

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  On Ubuntu 16.04LTS. Automatic package updater indicated grub2 needed
  updating. When it finished it said there was a problem and asked if I
  wanted to report it. After clicking 'Report it' no further action was
  taken at that time.  I have just rebooted, and the 'there was a
  problem' dialog box reappear, this time clicking 'Report it' elicited
  a password prompt and eventual display of this page.

  My system appears, on the surface, to be working correctly at the
  moment, but I have not done much since the reboot.

  Bug report #1692175 sounds similar but is for the efi version of grub.
